Question

The displacement is a function of x and t at x = 8.00 cm,
theparticles of the string motion is y= (3.50cm)sin[1.0-4.0(1/s)t]
. Awave is traveling on the string with speed 40cm/s. each one cm
ofthe string has a mass of 4.00grams. Calculate a) the wavelength
b)amplitude c) the tension in the string.
